    Opis:
    The experimental material consisted of 42 sows divided into 3 feeding groups, each containing 14 sows fed complete compound feed varying in protein content. Protein and amino acid content of the feed fed to the control group was in compliance with Polish standards. Protein content in the experimental groups was reduced by 10% and 20%, respectively. At the same time, lysine, methionine, threonine and tryptophane content was supplemented to the level of the control group. All pregnant and lactating sows were fed individually. The condition of the sows was determined by measuring the thickness of backfat at the P2 position on days 30 and 105 of pregnancy and on day 25 of lactation. The data analyzed in the study included: the total number of piglets born, their body weight gain, milk composition, weaning-to-estrus interval and the farrowing rate. Protein content of the compound feed did not have a significant impact on the increment in backfat during pregnancy and losses during lactation. The sows fed compound feed with reduced protein content gave birth to 0.7 and 0.6 less piglets per litter than the control animals. However, due to lower losses, they bred 0.3 and 0.4 more piglets than the control sows. Average body weight of a piglet on day 21 was 0.5 kg lower in the experimental than in the control group. Dry matter, protein, fat and lactose content of the sow’s milk did not depend on protein content of the feed. The weaning-to-estrus interval in the experimental groups was one day longer than in the control group. The reproductive rate accounted for 86% and was comparable in all the groups.

    The aim of the research, the results of which are presented in the paper, is to fabricate, by Selective Laser Melting (SLM), a metallic scaffold with Ti6Al4V powder based on a virtual model corresponding to the actual loss of a patient’s craniofacial bone. A plaster cast was made for a patient with a palate recess, and the cast was then scanned with a 3D scanner to create a virtual 3D model of a palate recess, according to which a 3D model of a solid implant was created using specialist software. The virtual 3D solid implant model was converted into a 3D porous implant model after designing an individual shape of the unit cell conditioning the size and three-dimensional shape of the scaffold pores by multiplication of unit cells. The data concerning a virtual 3D porous implant model was transferred into a selective laser melting (SLM) device and a metallic scaffold was produced from Ti6Al4V powder with this machine, which was subjected to surface treatment by chemical etching. An object with certain initially adopted assumptions, i.e. shape and geometric dimensions, was finally achieved, which perfectly matches the patient bone recesses. The scaffold created was subjected to micro-and spectroscopic examinations.
    Celem badań, których wyniki zaprezentowano w artykule jest wytworzenie, metodą selektywnego topienia laserowego (SLM), scaffoldu metalowego z proszku Ti6Al4V na podstawie wirtualnego modelu odpowiadającego rzeczywistemu ubytkowi kości twarzoczaszki pacjenta. Od pacjenta z ubytkiem podniebienia pobierano wycisk gipsowy, który następnie zeskanowano za pomocą skanera 3D, w celu uzyskania wirtualnego modelu 3D ubytku podniebienia, na podstawie którego z użyciem specjalistycznego oprogramowania utworzono model 3D litego implantu. Po zaprojektowaniu indywidualnego kształtu komórki jednostkowej, determinującej wielkość i trójwymiarowy kształt porów scaffoldu, poprzez multiplikację komórek jednostkowych przekształcono wirtualny model 3D implantu litego w model 3D implantu porowatego. Dane dotyczące wirtualnego modelu 3D implantu porowatego przetransferowano do urządzenia służącego do selektywnego topienia laserowego (SLM) i z użyciem tej maszyny z proszku Ti6Al4V wytworzono metalowy scaffold, który poddano obróbce powierzchniowej poprzez trawienie chemiczne. Finalnie otrzymano obiekt o założonych na wstępie: kształcie i wymiarach geometrycznych, które idealnie odpowiadają ubytkowi kości pacjenta. Wytworzony scaffold poddano badaniom mikro i spektroskopowym.

    Opis:
    The paper presents the results on the wear resistance of PVD coatings on cutting inserts made from sintered carbide and sialon ceramics. The exploitative properties of coatings in technological cutting trials were defined in the paper, which also examined the adhesion of coatings to the substrate, the thickness of the coating, and the microhardness. As a result, it was found that isomorphic coating with AlN-h phase of covalent interatomic bonds exhibits much better adhesion to the sialon substrate than isomorphic coating with titanium nitride TiN. These coatings assure the high wear resistance of the coated tools, and the high adhesion combined with the high microhardness and fine-grained structure assure an increase in the exploitative life of the coated tools. In the case of coatings on substrate made from sintered carbide, there was a significant influence on the properties of the tools coated with them as concerns the existence of the diffusion zone between the substrate and the coating.

    In this paper are presented the investigation results concerning microstructure as well as mechanical properties of the surface layer of cast aluminium-silicon-copper alloy after heat treatment alloyed and/ or remelted with SiC ceramic powder using High Power Diode Laser (HPDL). For investigation of the achieved structure following methods were used: light and scanning electron microscopy with EDS microanalysis as well as mechanical properties using Rockwell hardness tester were measured. By mind of scanning electron microscopy, using secondary electron detection was it possible to determine the distribution of ceramic SiC powder phase occurred in the alloy after laser treatment. After the laser surface treatment carried out on the previously heat treated aluminium alloys, in the structure are observed changes concerning the distribution and morphology of the alloy phases as well as the added ceramic powder, these features influence the hardness of the obtained layers. In the structure, there were discovered three zones: the remelting zone (RZ) the heat influence zone (HAZ) and transition zone, with different structure and properties. In this paper also the laser treatment conditions: the laser power and ceramic powder feed rate were investigated. The surface laser structure changes in a manner, that there zones are revealed in the form of. This carried out investigations make it possible to develop, interesting technology, which could be very attractive for different branches of industry.

    Opis:
    The aim of the investigations described in this article is to present a selective laser sintering and melting technology to fabricate metallic scaffolds made of pristine titanium and titanium Ti6Al4V alloy powders. Titanium scaffolds with different properties and structure were manufactured with this technique using appropriate conditions, notably laser power and laser beam size. The purpose of such elements is to replace the missing pieces of bones, mainly cranial and facial bones in the implantation treatment process. All the samples for the investigations were designed in CAD/CAM (3D MARCARM ENGINEERING AutoFab (Software for Manufacturing Applications) software suitably integrated with an SLS/SLM system. Cube-shaped test samples dimensioned 10×10×10 mm were designed for the investigations using a hexagon-shaped base cell. The so designed 3D models were transferred to the machine software and the actual rapid manufacturing process was commenced. The samples produced according to the laser sintering technology were subjected to chemical processing consisting of etching the scaffolds’ surface in different chemical mediums. Etching was carried out to remove the loosely bound powder from the surface of scaffolds, which might detach from their surface during implantation treatment and travel elsewhere in an organism. The scaffolds created were subjected to micro- and spectroscopic examinations
    Celem badań, opisanych w niniejszym artykule jest zaprezentowanie technologii selektywnego spiekania i topienia laserowego w celu wytworzenia metalowych scaffoldów z proszków: czystego tytanu oraz jego stopu Ti6Al4V. Techniką tą przy zastosowaniu odpowiednich warunków wytwarzania między innymi mocy lasera i wielkości plamki lasera wytworzono tytanowe scaffoldy o różnych własnościach i strukturze. Tego typu elementy mają za zadanie zastąpić brakujące fragmenty kości głównie kości szczękowo-twarzowych w procesie leczenia implantacyjnego. Wszystkie próbki do badań zaprojektowano w odpowiednio zintegrowanym z systemem SLS/SLM oprogramowaniem CAD/CAM (3D MARCARM ENGINEERING AutoFab, Software for Manufacturing Applications). Przy wykorzystaniu komórki bazowej o kształcie heksagonalnym zaprojektowano próbki do badań w kształcie sześcianu o wymiarach 10×10×10 mm. Tak zaprojektowane trójwymiarowe modele przetransportowano do oprogramowania maszyny gdzie rozpoczęto właściwy proces wytwarzania przyrostowego. Wykonane w technologii spiekania laserowego próbki poddano obróbce chemicznej polegającej na trawieniu powierzchni scaffoldów, w różnych ośrodkach chemicznych. Trawienie wykonano w celu usunięcia z powierzchni scaffoldów luźno związanego proszku, który mógłby podczas leczenia implantacyjnego oderwać się od ich powierzchni i przedostać się w inne miejsce organizmu. Wytworzone scaffoldy poddano badaniom mikro- i spektroskopowym.

    Opis:
    In this study, we assessed the effect of a humic-fatty acid preparation (HFA) used in rabbit feed on certain haematological and biochemical serum parameters (the lipid profile and the Ca, P and Fe contents). A higher RBC, HGB and HCT values were observed in the groups that were given HFA. An increase in Fe concentrations were also noted. The total and LDL cholesterol were lower in the groups which received HFA than in the control group.
